This is the same thing that has been on my mind for some time. Whats the difference between overninght passengers sleeping on the boat while it is tied to the bank and overnight guests in the Delta Queen Hotel sleeping overnight while the boat is tied to the bank? Could there be some loophole in the SAS law that would allow the boat to cruise for 12 hrs. as Capt John has pointed out and then tie up every night and continure the next day?
